Integrated amplifiers
Musical Fidelity M2SI
The Musical Fidelity M2si provides 72 watts per channel at 8 ohms and 137 watts at 4 ohms. This means that the M2 si will drive a wide range of speakers, even models with high power consumption. The fully discrete power amplifier, complemented by its dedicated power supply and lavishly designed toroidal transformer, guarantees reserves for proper peak power and wide dynamic range.

Musical Fidelity M3SI
The device is made according to the classical "double mono" scheme, which ensures the identity of the characteristics of the left and right channels. The level of its nonlinear distortion, measured at a frequency of 1 kHz, does not exceed 0.007%, and at a frequency of 10 kHz it is only 0.01%.
Integrated amplifiers
Musical Fidelity M5SI
The Musical Fidelity M5si integrated circuit is a representative of the M5s line. In terms of ideology, design and basic indicators, it is closer to the M6si than to the budget M3si. And although this model does not use nuvistors, the company positions it as the successor to the flagship Nu-Vista 800.
Integrated amplifiers
Musical Fidelity M6SI500
The Musical Fidelity M6 500i amplifier has a power of 500 watts per channel with an impedance of 8 ohms. The latest electrical circuit provides unsurpassed stability and linearity. The distortion is extremely small, at 0.008% at 1 kHz and 0.015% at 20 kHz. But what is even more significant is the low distortion at ultra-high frequencies. For example, at 30 kHz they are 0.02%, and at 50 kHz they are 0.2%. Its impeccable linearity and solid power reserve allow this amplifier to work with any speaker system.

Musical Fidelity M6SI STREAM
Internally, the M6si is configured as 2 independent monoblock power amplifiers with a separate preamp. In fact, it's a preamp with 2 monoblock power amplifiers that just happen to share the same case. It uses technology taken from our legendary 1kW TITAN power amplifier. And the combination of high power, high current and exceptional stability of the M6 means that it can easily control any speaker.
